Application filed October 3L 1905. Serial No. 285,249.

To all whom it may concern:

Be it known that I, MATTHEW J. FLAN- NERY, a citizen of the UnitedStates, and a resident of Bozeman, in the county of Gallatin and Stateof Montana, have made certain new and useful Improvements in -Door-Fasteners, of which the following is a specification. i

My invention is an im rovement in automatic door fasteners an consistsin certain novel constructions and combinations of parts hereinafterdescribed and claimed.

In the drawing Figure 1 is a perspective view of my improved fasteners.Fig. 2 is a central longitudinal section. Fig. 3 is a perspective viewof a modified form, and

ig. 4is avertical lon itudinal section of a mail box provided wit theform shown in In the resent embodiment of my invention, a late A havinga segmental portion 0,, provided with perforations (1. whereby it ma beattached to a door, is provided with ugs 0. at the side thereof, betweenwhich are received lugs 0, upon a catch C, a pivot pin a, traversingalined openings in the lugs being rovided for securing the catch and thep ate together. p

A spring 0 encircles the'pivot pin, one of the ends of the springengaging the catch and the other the plate, for maintaining the catch inits /operative osition. The tail 0 of the catch is provide with a pin 0,traversing a central opening a, in the segmental portion of the late anda registering opening in the door, the free end of the pin beingprovided with a knob 0 on the opposite side of the door for conveniencein manipulatin the catch.

The opposite end of the catch is bent downwardly and backwardly to forman abutment c", having a square inner face '0 and an inclined outer face0 A portion of the substance of the catch is struck u wardly to form alug 0 provided with an el dngated opening 0 the lug being at the extremeend 0 the catch.

A. second plate B, having a segmentalportion I), provided withperforations b whereby it may be attached to the casing or to theopposite door, is provided with an offset portion b for enterin betweenthe catch the free end of the second plate is bent upwardly and back.-wardly'to form an abutment b, having a gather.

square inner face I), for cooperatingwith the square face of theabutment c and an inclined outer face I) for cooperating with theinclined face of the abutment on the catch.

A lug b, is struck upwardly from the substance of the offset portion,the lug. being. arranged in such position that it will contact with thelug 0' when the plateis in osition beneath the catch, and being provi edwith an elongated opening b registering in such position with theelongated o ening on the lug c9. Stops (f, are provide upon the plate A,for engagin the abutment on the plate B, to, limit t e inward motionthereof, with respect to the plate A.

In the use of m improved fastener, the

plate provided wit the catch is secured to the door or to oneof thedoors, while the plate B is secured to the casing or to the other door.When the doors are moved towards each other, the inclined face of theabutment on the second plate enga es the inclined face of the abutmenton t e catch,

lifting the same and allowing the plate to ass inward to a positionwhere the square faces of the abutments will engage each other, toprevent withdrawal of the plate.

In' this position an ordinary pad lock may be inserted in the elongatedopenings of the lugs, to secure the parts of the fastener to- When it isdesired to release the portions of the'fastener, the tail of the catchis de ressed, thus' releasing the plate B, from etween the catch and theplate A.

In Fig. 3, I have shown a construction similar in all respects tothatshownin the remainin figures, except that the lugs for p the attacment of the. pad lock, the stops a and the pin and knob for manipulatingthe catch are omitted.

While I have described my invention asbeing applied to a slidin door, itis obvious that it might be used on liinged doors, as for instance, thedoors of rural free delivery mail boxes, and I have shown thisapplication in Fig. 4. It will be evident from the description that myimproved fastener is very simply constructed, it is not liable to easilyget out of order, and is adapted to a variety of uses. When used uponcar doors, a seal may be passed through the lugs instead of a pad lock.

The important advantage of my improved Having thus described myinvention what I claim as new and desire to secure by Letters Patentis 1. A fastener for sliding doors, comprisin' a plate havin a segmentalportion provide with perforations whereby to secure it to a door, aspring actuated catch pivoted to the plate, one end of the catch beingbent downwardto form an abutment having asquare inner face and aninclined outer face, said catchhaving an upwardly extendin lug adjacentto the abutment and formed cm the catch and provided with an opening, 'apin secured to theopposite endtofthe catch and .traversin an o ening inthe plate and the ,door, sai in sing provided with a knob for manipuating the catch, a second plate having a segmental portion provided withperforations whereby to attach it to the casing, and a portion offsetfrom the segmental portion for'entering between the first plate and thecatch, the free end. of the second plate being bent upwardly to form anabutment having a square inner face and an inclined outer face forcooperating with the first abutment, said second plate being proyidedwith a lug having an openingir'egister ing with-the opening in the firstlug, and said first plate having stops for engaging the abutment on thesecond plate where y to out preventing limit the inward movement oftheplates with res eat to each other. 2: A astener forsliding doorscomprising a pla'te having-asprin actuated catch ivoted to the upperface t ereof, a second p ate having'a portion for enterin between thecatch and the first plate, the st plate havingstopsfor' limiting theinward movement of the second plate, said catch and second plate beingprovided with lugs havin registering openin s, and-with-abutmentsfiVlIlg square inner aces and inc-lined outer faces,

said abutments being on the en aging faces of, said catch and second pate, means wherebyto attach the plates to the door-and the casing, andmeans for manipulatifigthe catch.

3. A fastener comprising a plate having a springsactuated catchconnected thereto, a second plate havin a portion-for enterin betweenthe-first p ate and the catch, sai first platehaving meansbeneath thecatch for engaging the second late to limit the inand catch beingprovided withmeans whereby to allow the second plate'to enter beneaththe catchqand to prevent the removal therefrom, and meansfor releasingsaid last named means.
